Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a novel trough-type mixer structure. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, the contact surface area of ​​the materials can be increased to promote chemical reactions and accelerate physical changes. Commonly used mixers are divided into four main categories: gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixers, and powder and granular solid material mixers.

[0003] In the existing technology, the three-section mixing shaft can be disassembled and replaced. However, the three-section mixing shaft is usually connected and fixed in the mixing chamber with screws. This may cause nuts and screws to fall off during the mixing process, contaminating the mixed food materials, causing safety hazards, and making it impractical.

[0004] Therefore, a new type of trough-type mixer structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel trough-type mixer structure, which aims to solve the problems in the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a novel trough-type mixer structure, comprising:

[0007] frame;

[0008] The mixing hopper is mounted on the frame.

[0009] Two bearing seats are symmetrically installed on the top side of the frame. Both bearing seats are coaxially arranged with the stirring frame. A hollow sleeve is connected to the inner wall of each bearing seat. A rotating shaft is installed inside each hollow sleeve. A fixing component is provided between each rotating shaft and the hollow sleeve. The fixing component is used to connect the hollow sleeve and the rotating shaft so that the rotating shaft rotates with the rotation of the hollow sleeve.

[0010] A mixing rack is installed inside the mixing hopper. Both ends of the mixing rack are equipped with a snap-fit ​​assembly and a support assembly between them and the two rotating shafts. The snap-fit ​​assembly is used to connect the rotating shafts and the mixing rack so that the mixing rack rotates with the rotating shafts. The support assembly is used to support the mixing rack to prevent it from sinking.

[0011] Preferably, the snap-fit ​​assembly includes a first snap-fit ​​chuck, a snap-fit ​​groove, a second snap-fit ​​chuck, and snap-fit ​​blocks. The first snap-fit ​​chuck is connected to the outer surface of the end of the rotating shaft.

The second snap-fit ​​chuck is connected to the outer surface of the end of the stirring rack. There are multiple snap-fit ​​blocks, which are evenly distributed on one side of the second snap-fit ​​chuck. Each snap-fit ​​block snaps into the snap-fit ​​groove, and each snap-fit ​​block corresponds to a snap-fit ​​groove.

[0012] Preferably, the fixing component includes a fixing hole one and a fixing hole two. The fixing hole one is formed on the outer surface of the hollow sleeve, and the fixing hole two is formed on the outer surface of the rotating shaft. A fixing bolt is threadedly connected to the inner wall of the fixing hole two and the fixing hole one.

[0013] Preferably, the support assembly includes a support rod, a support inner hole, and a seal. The support rod is connected to the end of the rotating shaft. The support inner hole is opened at the end of the stirring frame. The support rod is inserted into the interior of the support inner hole. The support rod is coaxially arranged with the rotating shaft. The seal is disposed on the support rod and is used to ensure the sealing between the support rod and the stirring frame.

[0014] Preferably, the sealing element includes an annular sealing groove and a sealing ring, the annular sealing groove being formed on the outer surface of the support rod, and the sealing ring being disposed inside the annular sealing groove.

[0015] Preferably, the stirring frame includes a stirring shaft, stirring rods, and stirring blades.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 7As shown, a novel trough-type mixer structure includes a frame 10, on which a mixing hopper 11 is mounted. A mixing frame 20 is disposed inside the mixing hopper 11. Two bearing seats 12 are symmetrically mounted on the top side of the frame 10, both bearing seats 12 being coaxially arranged with the mixing frame 20. A hollow sleeve 13 is connected to the inner wall of each bearing seat 12. A rotating shaft 14 is installed inside each hollow sleeve 13. A fixing component is provided between each rotating shaft 14 and the hollow sleeve 13, connecting the hollow sleeve 13 and the rotating shaft 14 so that the rotating shaft 14 rotates with the rotation of the hollow sleeve 13. A snap-fit ​​component and a support component are provided between each rotating shaft 14 and the mixing frame 20. The snap-fit ​​component connects the rotating shaft 14 and the mixing frame 20, allowing the mixing frame 20 to rotate with the rotation of the rotating shaft 14. The support component supports the mixing frame 20 to prevent it from sinking.

[0031] The mixing rack 20 can be quickly clamped and fixed by the snap-fit ​​components and the fixing components. No screws and nuts are needed during the fixing process, thus avoiding the possibility of screws or nuts contaminating food materials.

[0032] It should be noted that the bottom of the mixing hopper 11 is connected to a discharge pipe, and a control valve is installed on the discharge pipe. The material that has been mixed inside the mixing hopper 11 can be discharged through the discharge pipe and the control valve.

[0033] like Figure 3-7 The snap-fit ​​assembly includes a first snap-fit ​​15 connected to the outer surface of the end of the rotating shaft 14 and a second snap-fit ​​21 connected to the outer surface of the end of the stirring rack 20. A plurality of snap-fit ​​grooves 151 are evenly opened on one side of the first snap-fit ​​15, and a plurality of snap-fit ​​blocks 22 are evenly connected on one side of the second snap-fit ​​21. The snap-fit ​​blocks 22 snap into the interior of the snap-fit ​​grooves 151, and the snap-fit ​​blocks 22 correspond one-to-one with the snap-fit ​​grooves 151. The fixing assembly includes a first fixing through hole 131 opened on the outer surface of the hollow sleeve 13 and a second fixing through hole 141 opened on the outer surface of the rotating shaft 14. A fixing bolt is threadedly connected to the inner wall of the second fixing through hole 131. The fixing bolt is not shown in the figure.

[0034] When fixing the mixing frame 20 inside the mixing hopper 11, the mixing frame 20 is placed inside the mixing hopper 11 and the axis of the mixing frame 20 is aligned with the axis of the rotating shaft 14. Then, the rotating shaft 14 is moved along the axial direction of the hollow sleeve 13. At this time, the chuck 15 moves accordingly, so that the locking block 22 is locked into the locking groove 151 and the chuck 15 and chuck 21 fit tightly together. At this time, the positions of the fixing hole 131 and the fixing hole 241 are aligned. Then, the fixing bolt is threaded to the fixing hole 131 and the fixing hole 241 to fix the rotating shaft 14 and prevent the rotating shaft 14 from moving. At this time, the mixing frame 20 is clamped and fixed by the chuck 15 and the chuck 21, and the fixing operation of the mixing frame 20 is completed, so that the fixing process of the mixing frame 20 does not require the use of screws or nuts.

[0035] It should be noted that both the first fixing hole 131 and the second fixing hole 141 are located outside the mixing hopper 11 to prevent the fixing bolts connected to the first fixing hole 131 and the second fixing hole 141 from falling into the mixing hopper 11. Furthermore, during the movement of the rotating shaft 14, external force can be applied to the rotating shaft 14 through external equipment to keep the rotating shaft 14 and the mixing frame 20 in a pressed and compacted state, thus ensuring the stability of the connection between the rotating shaft 14 and the mixing frame 20.

[0036] like Figure 5-7 The support assembly includes a support rod 16 installed at the end of the rotating shaft 14 and a support inner hole 201 opened at the end of the stirring frame 20. The support rod 16 is inserted into the interior of the support inner hole 201 and is coaxially arranged with the rotating shaft 14. A sealing element is provided on the support rod 16 to ensure the sealing between the support rod 16 and the stirring frame 20.

[0037] The sealing element includes an annular sealing groove 161 formed on the outer surface of the support rod 16, and a sealing ring 17 is provided inside the annular sealing groove 161.

[0038] After chuck 15 and chuck 21 are tightly fitted together, the support rod 16 is inserted into the inner hole 201 of the support. This counteracts the gravity of the stirring frame 20 and distributes the load borne by the stirring frame 20, while also restricting the degree of freedom of the stirring frame 20, thus preventing the stirring frame 20 from sagging. The annular sealing groove 161 and the sealing ring 17 ensure the sealing between the support rod 16 and the stirring frame 20, preventing liquid from entering the inner hole 201 of the support during the stirring process.

[0039] It should be noted that the support rod 16 and the support inner hole 201 can be fitted with an interference fit so that the support rod 16 will not easily shift after being inserted into the support inner hole 201, thus ensuring the stability of the connection between the support rod 16 and the stirring frame 20.

[0040] like Figure 3-5 The stirring rack 20 includes a stirring shaft 23, a stirring rod 24 is connected to the outer surface of the stirring shaft 23, and a stirring blade 25 is fixedly connected to the end of the stirring rod 24. The stirring blade 25 is arranged in a spiral.

[0041] During the mixing process, the stirring shaft 23 rotates with the rotating shaft 14 under the connection of the snap-fit ​​component and the fixing component. At this time, the stirring rod 24 drives the stirring blade 25 to rotate and stir and mix the materials inside the mixing bin 11.

[0042] like Figure 1 and Figure 3-4 A protective cover 18 is installed on the frame 10. A drive structure 30 is provided inside the protective cover 18. The drive structure 30 is connected to a rotating shaft 14. The drive structure 30 is used to drive the rotating shaft 14 to rotate. The drive structure 30 includes a drive motor 31 installed inside the protective cover 18. The output end of the drive motor 31 is connected to a sprocket 32. The sprocket 32 ​​is connected to a sprocket 33 via a chain drive. The sprocket 33 is connected to the rotating shaft 14.

[0043] During the mixing and stirring of materials, the drive motor 31 is started, and the rotating shaft 14 is rotated under the transmission action of sprocket 1 32, chain and sprocket 2 33. At this time, the stirring frame 20 will rotate accordingly and perform stirring and mixing operations on the materials.

[0044] like Figure 1 Bearing housing 2 19 is fixedly installed on two symmetrical sides of the mixing hopper 11. Bearing housing 2 19 is coaxially arranged with bearing housing 12. The rotating shaft 14 passes through the inside of bearing housing 2 19 and extends into the inside of the mixing hopper 11. The inner diameter of bearing housing 2 19 is matched with the diameter of rotating shaft 14. Bearing housing 2 19 is used to support rotating shaft 14 to ensure the stability of rotating shaft 14 during rotation.
